[0002] Sheet metal is a comprehensive cold processing technology for metal sheets, including shearing, folding, welding, riveting and splicing. Its notable feature is that the thickness of the same part is consistent. The products processed by sheet metal processing are called sheet metal parts. The sheet metal parts referred to in different industries are generally different, and are mostly used for assembly. Stamping is a forming processing method that relies on presses and dies to apply external forces to plates, strips, pipes and profiles to cause plastic deformation or separation, thereby obtaining the required shape and size of the workpiece. Stamping and forging belong to plastic processing, collectively known as forging. The blanks for stamping are mainly hot Rolled and cold rolled steel plates and strips, stamping dies, are special process equipment used to process materials into parts during cold stamping, called cold stamping dies. Due to the uneven force applied to some stamping dies during the stamping process, or the unstable downward pressure of the stamping dies, sheet metal debris may splash and cause accidental injury to workers, increasing the risk of workers working. In addition, workers may be accidentally injured by the press due to distraction during the stamping process. Therefore, a protective device for precision sheet metal stamping is proposed to solve the above problems. Utility Model Content
